CELLULAR RADIATOR Specification of Letters Patent.

Patented Sept. 24,1918.

Application filed March 20, 1916. Serial No. 85,306.

To all whom it may concern:

Be it known that I, Enwanu' S. ERIoKsoN, a citizen of the United States, residing at Detroit, in the county of lVayne and State 6 of Michigan, have invented certain new and useful Improvements in Cellular Radiators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in 10 the art to which it appertains to make and use thesame.

My present invention relates to sci-called cellular radiators, such as extensively used in connection with automobiles including explosive engines, and is in the nature of an improven'lent on or modification of the radiator disclosed and broadly claimed in my Patent No. 1,233,765, of (late July 17, 1917, and entitled Cellular radiator.

(.ii-enerzidly stated, the invention consists of the novel construction and combination of parts hereinafter described and defined. in

the claims.

The iniproved radiator is illustrated in 26 the accompanying drawings wherein like characters indicate like parts throughout the several views] Referring to the drawiiigsz Figure 1 1s a perspective view showing 30 mic of the radiator plates as it appears after having first been stamped to form;

[Fig 2 is a view of the parts shown inl i 1 with the plates bent about hall. way to a position in which the two parts thereof form a radiator unit with a zigzag air channel between them;

Fig. 3 shows the plate illustrated in Fig 1 and 2 folded together to form a radiator unit;

Fig. 4 a front elevation showing two radiator sections scparijitcd from each other but adapted to be put together to toru'ra zigzag water channel between the :nljacent plates of the two units; and 46 Fig. 5 is a view corresponding to Fig. 4, but showing the two units connected to form the zigzag water channel between) the connccted plates of the two units.

The general arrangement and operation of 50 cellular rmliatrn-s, as applied to automobiles and analogous uses, are well iuulerstoml, and for the purposes of this case, it need only be stated that a desired number of units will he assei'nliilcd, as illustrated in l ig. 5, to I form the complete radiator core with the the lower core of the radiator made up of a multiplicity of thin sheet metal plates 'n'cterably brass) that are bent into zigzag form and adapted to be put together in pairs to form zigzag air channels or zigzag water tubes, as the case may be, but in the con .struction illustrated, are 1. rimai.-ily assembled to form zigzag air channels, and the units asson'ibled and connected to form the zigzag water tubes between the adjacent units, or in some instances, the arranges inent may be reversed, As a feature of this invention, the zigzag plates .for forming the 'adiator units are first stamped -or pressed into form, as a single sheet, partly but not entirely separated on a proper bending line, and are then bent and folded, together, or into parallel arrangen'ient.

Betta-ring first to Fig. 1, it will be noted, that the metallic sheet is bent to form two zigzag or fluted platesl-E; that the tinting or corrugations of the zigzag plates l--2, in the vertical cross section of the radiator, follow zigzag lines forming adjacent surfaces at angles atlZO degrees; that the plate 2 is of'l'set from the plate I and that the flat outer sin-limos of the ridges of plate 2 are in the plane of the lat inner surfaces of tho depressions in the plate 1. Stated in au other way, the longitudinally aliucd flutes or corrugations in the two plates 1 and 2 are rercrscly bulged so that. at their abutting edgcs they outline hexagonal cellular "lorunilions. 'lln angular outer edge of the plate 2 is laterally ol'l' at slightly, as indirated at 2 for a purpose which will presently appear. auditor a similar purpose, the angular inner edge portion o'l said plate is rorrcspondiugly otl'set laterally at- 2". The said angular olt'sct portion 2" is alined, with .-a like angular or zigzag spacing and uliuing web 3 from which it is severed by slits 4 that are out through the three sides of the outprcssvd angular three raised sides o'l each llutc, but are left integral at the aliued bottom web portions, so that the said adapted to be bent and folded together at 5 (see Figs. 1 and \Vhrn the two plate 1 and are folded tonether, the so-called spacing and alined webs plates 1 and 2 are 3 project beyond the adjacent edge of the plate .1 and therewith form hexagonal formations.

The outer edge of the plate 1, in a similar manner to the outer edge of the plate 2, is laterally offset at 1*, and beyond these ofisets, is formed with a zigzag spacing and alining web 3.

The webs 3 and 3 are severed from the plate 1, except at the bottoms of the angular depressions, and each web 3 is alined with a corresponding web 3 in a direction longitudinally of the corrugations of the plate.

When the two plates I. and -2 are first pressed, as shown in Figs. 1 an .2, and then folded together, as shown in Fig. 3, the fiat bottoms of the web 3 of the plate 1 Will be brought into contact with the flat bottoms of the angular edge portions 2 of the plate 2, and the unscvered web which connects the angular edge portion 2 of the piate with the web 3 will be folded together fiatwise. thus forming a so-called unit, one of which is shown in Fig. 3 and two of which are shown in Fig. 4. The unit thus formed will. have a zigzag vertically extended air passage or channel y, and when the units are put together, as shown in Fig. 5, the connected plates thereof will form. a zigzag water tube :Z/ *Of course, any desired number of these units may he put together, and when put together, the contacting portions of their edges will be united, preferably by solder, so as to seal the front and rear edges of the water tubes. The zigzag air channels will, of course, be open both at front and rear of the radiator core.

Obviously, with the above described construction, it is a very easy matter, first to properly connect the plates of the unit and then to connect the units, and no great skill or care is required to effect the proper asseniblage and alinement of these plates.

This, together with the fact that the plates spacing and alining web partii may be stamped at very small cost, affords a highly efficient radiator core that may be constructed at low cost.

Furthermore, the radiator core is given the appearance of a truly cellular structure in which the cells are he .a

What I claiiin is:

1. A radiator unit in thin sheet metal bent to form two n with alined corrugations bulged in directions and united by a cor gated spacing and alining web partly severed from both plates, but integral J1me with, the said two plates id gether to form the unit.
